Public bug reported:
Monit has a start delay timer, to prevent service from starting other
services too early (before they are ready). This bug has been reported
to monit developer and is fixed with commit
https://bitbucket.org/tildeslash/monit/commits/2dae91df32ac7bd0e02c6e6ee8522e75958f4324.
Main problem here is, that boot time is read from /proc/stat
# grep btime /proc/stat
This boot time is from host though and a wrong reference in this case.
It differs from /proc/uptime.
It is probably a major bug, because it can disrupt boot order. If monit
starts pretty early and detects other services are not running, it will
immediately (re-)start them. In case of apps with databases, this could
lead to problems.
